Thanks for the nice words! I have more detailed pics of the convertible that I will try to post later today.
Gustav: In fact all three of them have the "ugly" standard orange turn signal bulbs...

But I should probably get white ones.
Yes, all body parts (of the car) are painted Alpina Blue which is very nice!
Frosty: I have to get my hands on a copy of BMW Car. Your car must be the one that was advertised by BMW Niederlassung Berlin? If so, I think you made a good choice

All my cars came with the M3 style mirrors from Alpina. It was an option back then.It makes the cars look a lot better IMHO. In fact the Coupe and Convertible also came with gold Alpina deko stripes, but the first owners took it off... Honestly I think the cars look better without...I will probably get a lot of heat here for that statement
